Port 895c3219 Original Commit Message: Replacing pc with trampoline on stack This CL is the follow up of https://chromium-review.googlesource.com/c/586707/ which used to crash when running the gc-stress bots. It seems to be working now. We now keep the trampoline PC in the Safepoint table and use that information to find SafepointEntries. There's some refactoring that can be done, such as changing the code for exceptions in a similar way and removing the trampoline from the DeoptimizationInputData. Will take care of this in the next CL.

My goal was to move breakpoint API to native with minimal changes around, so on inspector side we use v8::debug::BreakpointId instead of String16, on v8::internal::Debug we use i::BreakPoint object instead of break point object created inside of debug.js. There are a lot of opportunities how we can improve breakpoints (at least we can avoid some of linear lookups to speedup implementation) but I think that as first step we need to remove mirrors/debug.js APIs. Drive by: debugger-script.js and usage of debugger context in inspector code base.

Karl Schimpf authored
This CL does the first baby steps on moving the current (experimental) exception handling to match that of the WebAssembly proposal. It does the following: 1) Use exception tags instead of integers. 2) Only handle empty exception signatures (i.e. no values associated with the exception tag. 3) Only handle one catch clause. 4) Be sure to rethrow the exception if the exception tag does not match. Note: There are many things that need to be fixed, and are too numerous to list here. However, the code should have TODO's on each missing parts of the implementation. Also note that the code currently doesn't handle nested catch blocks, nor does it change the throw value being an integer. Rather, the integer value is still being thrown, and currently is the exception tag. Therefore, we don't build an exception object. This is the reason why this CL doesn't handle exceptions that pass values. Also, the current implementation still can't handle multiple modules because tag resolution (between) modules has not be implemented yet.

There's an inherent trade-off when deciding between ATOM and IRREGEXP regexps: IRREGEXP is faster at runtime for all but trivial single-character patterns, while ATOM regexps have a lower memory overhead. This CL is intended to help investigate impact on benchmarks and real-world code - if something tanks, it's easy to revert, otherwise it can be a first step towards a possible removal of ATOM regexps.

This adds support to materialize objects when generating a frame summary for an optimized frame via {OptimizedFrame::Summarize}. Note that this means each summary might re-materialize objects and hence produce new object identities every time. All use sites need to be able to cope with such semantics.

Replacing pc with trampoline on stack This CL is the follow up of https://chromium-review.googlesource.com/c/586707/ which used to crash when running the gc-stress bots. It seems to be working now. We now keep the trampoline PC in the Safepoint table and use that information to find SafepointEntries. There's some refactoring that can be done, such as changing the code for exceptions in a similar way and removing the trampoline from the DeoptimizationInputData. Will take care of this in the next CL.

This is a partial reland of "Allow a minimum semi-space size of 512K." with a heuristic to keep 1MB initial semi-space size for high memory devices.

Until now, when generating a builtin, it can only embed builtins (as call targets) that have already been generated. This is either achieved by reordering the builtins list, or by loading the call target at runtime from the builtins list (see MacroAssembler::TailCallBuiltin). This patch works around this issue by filling the builtins list with dummy code objects, which are later replaced with the completed actual builtins. In release mode, this adds around 3ms to 140ms we previously needed to populate the builtins list.
